The music for Catacomb 3-D was composed in Sequencer Plus Gold, exported to 
MIDI, and then converted to IMF. This is not the original MIDI file, the 
original MIDI file has been lost. Instead, this is a recreation made by Bobby 
Prince to show what the original would have been like. It was downloaded from 
Prince's Web page, but it is no longer available there.

This MIDI version is considerably longer with added percussion later in the 
song's loops. This same song was was used for Commander Keen 4 as well.
